BRUSH ATTACHMENT non WASHING MACHINES.

Application filed'november 12, 1921, Serial No. 514,533 Renewed January4, 1927. I

This invention relates to a brush'attachment for washing machinesprimarily designed iorbeing secured'to the shiftable wringer nowcommonly used in connection with power washing machines of varioustypes. i Excessively soiled garments cannot be washed clean bymost ofthe power machines now on the market, such garments requiring 1o rubbingupon a washboard, and to eliminate this arduous labor I provide a brushattachment which may be used in connection with a washing machinewringer of any type, andcwhereby excessively soiled garments may bereadily washed with but little labor on the part of the operator.

Further objects of the invention are to provide a device of thecharacter described which may be readily appliedto a washing structionof the latter,-which is simple in its construction and arrangement,strong, durable and eflicient in its use, and'comparatively inexpensiveto manufacture.

To the accomplishment of these and such otherobjects as may hereinafterappear the invention consists of thenovel construction, combination andarrangement of parts herein specifically described, and illustrated inthe accompanying drawings wherein is shown an embodiment of theinvention, but it is to be understood that changes, variations, andmodifications may be resorted to which comewithin the scope of the claimhereunto appended. 1

brush attachment. a

Referring in detail tothe notes the tub-of a cylinder type washing machine, provided at onecorner with the usual vertically disposed housing 2 which encloses thepower transmission for operating the wringer element 3.

1 A brush roll support 4 is positioned horirollers illustrating theircon- I drawings (1e;

zontally on thefront of the wringer element 3 slightly below thecontacting portion of the wringer rolls 5-. The support 4 is formed topartially enclose the'brush' roll 6 to prevent the splashing of thewater duringv the operation of the latter. a

I The top member ;7 of the support 4 serves 4 as a uide' board for thewringer element 3 to acilitate the feeding of the clothes to the wringerrolls. The member 7 is fiat and declines forwardly, as clearlyillustrated in Figure 4 of the drawings; I

One end of the support 4 is provided with a rearwardly projecting andintegrally formed bracket arm 8, and the other end thereof with anadjustable bracket arm 9. The support 4, adjacent to this end, isformed,with a longitudinal slot 10 for the passage of the adjusting screw 11which threadably engages, as at 12,'the securing leg 13 of the bracketarm '9. The bracket arm 9 carries a clamping'screw 14 for securelyattaching I the support 4 to the wringer element. By

this construction of the bracket arms the support 4 may be convenientlyattached to wringer elements of varying widths.

' The brush roll 6 is mounted on the shaft 15 which latter is suitablyjournaled, as at 16, in the end members 17 of the support 4.

The brush r0116 is preferably built in sections to permit of theinterchanging or replacement ofsuch sections, thereby elimi nating thenecessity of discarding the entire brush roll should only sectionsthereof be worn from use. One end of theshaft 15 carries a fixed collar18 provided with a stud 19. One. of the brush roll sections abutsagainst the collar18 and'is provided with an aperture 20 engaging thestud 19, thereby providing for the rotation ofthe brush roll with theshaft 15. Abutting sections of the brush roll are provided with a dowel21 engagingalined apertures 22 in respective brush roll sections. Theend of the shaft remote from the collar 18 is threaded, as at 23, andengaged by the nut 24, for securely clamping the several sectionsagainst the collar 18 and on the shaft 15.

A pair of backing or scrubbing rollers 25 are positioned forwardly ofthe'brush roll 6 and are adapted for holding the clothes against thebrush roll during the washing or scrubbing operation. The rollers 25 are'rotatably mounted at each end thereof, as shown at 26, in a bearingplate'QT, which latter is securely-held in position by a tie-rod 28. I 1V I Each end of thesupport 4 is provided with a forwardly projecting arm29 substantially T-shaped in transverse cross section. A carrier 30 isslidably mounted on each of the arms 29 in a manner clearly illustratedin Figure 7 of the drawings.- Each of the carriers 30 is formed with abearing aper ture 31 for the reception of the study32 car ried bythebearing plates'27, thereby pivotally connecting the rollers 25 with thecarriers 30. The aperture 31- in each of the carriers 30 istaperedinwardly, as at 33;, to provide and compensatefor a vacillatorymovement concomitant to the operation of the rollers 25 due to theunevenness of the bulk of clothes washing.

Each of he arms 29 is formed with a vertically disposed portion 34provided with a threaded aperture 35 for the engagement of thetensioning screw 36. The inner end of thetension screw 36 carries a coilspring 37 which extends into the pocket 38formed in the enlarged end ofthe carrier 30. By the adjustment of the screws 36 the rollers 25 may betensioned against or released from the brush roll 6. r

The shaft 15 is provided with anextension 39 which carries the pulley40, fixed thereto.

A casing comprising two sections 41 and 42 respectively is securelyclamped to the In the operation of my improved brush attachment theclothes to be washed are positioned between the brush roll 6 and thescrubbing or backing rolls 25. The action" of the brush roll will tendto. feed the clothes between the brush roll and the backing rollers, butthe clothes may be held by the operator and retard such feeding action,thereby permitting the washing or scrubhing of any portion of theclothes which may be excessively soiled until thoroughly cleaned. lVhenthe garment has been almost fed past the brush roll, the end thereof maybe started through the wringer element whereby the garment isautomatically drawn back over the brush roll and through the wringer.The brush roll, rotating in the clockwise direction and at considerablespeed, will provide an intense scrubbing action during such returnmovement of the garment.

- What I claim is: V

A scrubbing attachment for washing machines comprising a support in theform of a housing, rotatable scrubbing elements carried by the support,and means carried by the support for detachably connecting said supportto a wringer, the upper portion of said housing constituting a guide.

In testimony whereof I afiix my signature.
